<First embodiment>

Hereinafter, a first embodiment for carrying out the present invention will be described with reference to the drawings. In the drawings, the first to theteenth drawings are diagrams showing the first embodiment of the present invention.

1 is a plan view showing a liquid container according to the present invention, and FIGS. 2(a) and 2(b) are views showing a combination of an outer container and a liquid container, and FIG. 3 is a view showing the outer package. A side cross-sectional view of a combination of a container and a liquid storage container, and Figs. 4(a), (b) and (c) are views showing the action of the present invention.

In the present embodiment, the packaging container and the liquid storage container are The assembly includes an outer packaging container 5 made of synthetic resin, and the outer packaging container 5 has an opening 5a that is provided to be offset (disengaged) from the first central portion L1 that passes through the central portion of the upper surface. a position; and a liquid storage container 1 disposed in the outer packaging container 5.

The outer packaging container 5 may have an opening 5A above the outer packaging container 5 in addition to the opening 5a (please refer to FIGS. 2(a) and 2(b)).

In this case, the liquid storage container 1 is not inserted into the opening 5A, but when the liquid storage container 1 is inserted into the outer packaging container 5 and fixed to the opening 5a, the opening 5a can be used as a confirmation. A visual hole in the state of the liquid storage container 1 in the outer packaging container 5 is used.

In addition, the liquid storage container 1 has a rectangular bag main body 3 and an outflow port 40 provided at a position where the bag main body 3 is displaced (disengaged from the second central portion L2 passing through the central portion of the upper edge 3a). The outflow port 40 is attached to the opening 5a of the outer packaging container 5.

Next, the liquid storage container 1 will be further described.

The liquid storage container 1 is provided with the multi-layer film 2 in which the inner bag 21 is superposed on each other so as to overlap the outer bag 20 and the inner bag 21, and the four sides are heat-sealed. The heat seal portion 10 is formed, and the outflow port 40 is previously thermally fused between the inner bags 21 disposed on the upper edge 3a of the bag body 3.

In the present embodiment, the bag body 3 is obtained by "laminating the multilayer film 2 so that the inner bag 21 faces each other, and heat-sealing the four sides to form the heat seal portion 10". However, the present invention is not limited thereto, and for example, the inner bags 21 may be opposed to each other. After the multilayer film 2 is bent, three sides of the periphery other than the overlap are heat-sealed. Further, each of the inner edges of the heat seal portion 10 may be formed such that its inner edge is curved. As a result, it is a structure in which it is difficult for the fluid content to remain in the corner portion. Further, the bag body does not have to be composed of a multilayer film, and the film structure of the bag body 3 can be appropriately selected depending on the content or amount.

As described above, the bag body 3 is obtained by laminating two sheets of the multilayer film 2 and heat-sealing the periphery to form the heat seal portion 10. In this case, the bag body 3 has a rectangular shape having "the upper edge 3a, the bottom edge 3b, and the 2 side edges 3c, 3c". Further, the upper edge 3a includes two upper edge heat seal portions 10a, and the bottom edge 3b includes one bottom edge heat seal portion 10b, and each of the side edges 3c, 3c has one side edge heat seal portion 10c, and the upper edge heat is The sealing portion 10a, the bottom edge heat sealing portion 10b, and the side edge heat sealing portion 10c constitute the heat sealing portion 10.

Further, the upper edge 3a of the bag body 3 includes two upper edge heat seal portions 10a as described above. In this case, when the heat seal portion 10a of the upper edge 3a is divided into two, as in the case where one heat seal portion having the width of the two heat seal portions 10a is formed on the upper edge 3a, Edge 3 becomes softer. In addition, even if the upper edge heat seal portion 10a is not limited to two, the effect of the present invention can be obtained. Therefore, it can be set to one (please refer to FIG. 18) or three or more.

When the technique of the present invention is carried out, the multilayer film 2 is not limited to the two-layer structure in which "the outer bag 20 and the inner bag 21 are overlapped", and the "more than one middle bag 22" may be used. The three-layer structure may also be a single-layer structure formed only by the inner bag 20 or the outer bag 21.

Further, the outflow port 40 has an outflow port mounting portion 50 that is thermally fused to the upper edge 3a of the bag body 3, and an outflow port body 41 that is connected to the outflow port mounting portion 50 and protrudes outward from the bag body 3, The upper end of the outflow port body 41 is provided with an outflow port flange 42. Further, as shown in Fig. 1, the outflow port 40 is thermally fused between the inner bags 21 of the multilayer film 2 by the outflow port mounting portion 50.

As shown in FIGS. 5 to 9 , the outflow port mounting portion 50 of the outflow port 40 has a center portion 51 and a side portion provided on the center portion 51, and is thinner than the center portion 51. The elliptical cylinder of the thin portion 52" is formed in a flat shape and has a through hole 45 in the central portion 51. In general, when the outflow port 40 is thermally fused between the inner bags 21 of the multilayer film 2 by the outflow port mounting portion 50, it is easy to be surrounded by the "end portions of the inner bag 21 and the outlet port mounting portion 50". There are gaps in the fields that result in poor sealing. In order to prevent the above, the thin portion 52 is provided on both sides, and when the heat is melted, the gap can be prevented from being generated by the melting of the thin portion 52.

Further, the outlet body 41 of the outflow port 40 is formed by a tubular body having a substantially U-shaped cross section, and an outlet flange 42 is provided on the periphery of the upper end. An opening 44 is formed in the bottom portion 43 of the outflow port body 41. After the outlet 40 is attached to the outer packaging container 5, the opening 44 ensures the ventilation of the space between the outer packaging container 5 and the liquid storage container 1 and the outer packaging container 5, and is extruded during use ( When the content liquid is extracted, the gas can be sealed between the liquid storage container 1 and the outer packaging container 5 through the opening 44, and the pressure of the outside of the liquid storage container 1 can be smoothly applied to perform the extraction of the content liquid inside the liquid storage container 1.

Further, as shown in Fig. 3, the outflow port body 41 of the outflow port 40 is provided with a male screw 41A, and an internal thread 5A engageable with the male screw 41A is provided in the opening 5a of the outer casing 5. Then, by screwing the male screw 41A of the outflow port 40 into the internal thread 5A of the opening 5a, the outflow port 40 can be surely fixed in the opening 5a. In this case, the outflow port flange 42 of the outflow port 40 is attached to the opening 5a formed in the outer casing 5, and the liquid storage container 1 is supported in the outer casing 5.

The external thread 41A of the outflow port 40 and the internal thread 5A of the opening 5a constitute a fixing means.

The outflow port 40 is preferably manufactured by injection molding. The resin used for the outflow port 40 is not particularly limited as long as it can be molded, but it can be thermally fused with the "resin constituting the inner surface of the inner bag 21 of the multilayer film 2". The bonding is appropriately selected depending on the resin constituting the inner surface of the inner bag 21. Generally, it is suitable for "high-density polyethylene which has rigidity at a high temperature and is not easily embrittled at a low temperature".

Further, as shown in FIGS. 5 to 9 , the thin portion 52 on both sides of the central portion 51 of the outflow port mounting portion 50 of the outflow port 40 is formed with a notch portion 55 at a lower end portion thereof. The notch portion 55 may be formed together when the outflow port 40 is formed, or may be formed in the outflow port 40 (in the case where the lower end corner portion of the outflow port mounting portion 50 does not have the notch portion 55), and then in the outflow port mounting portion 50. The lower end corner portion forms a notch portion 55. Further, each of the cutout portions 55 has a plurality of stepped portions 55a of, for example, 3 to 10 layers, and these stepped portions 55a function as positioning scales when the air outlet attachment portion 50 and the bag body 3 are thermally fused.

In other words, the outflow port mounting portion 50 of the outflow port 40 is thermally fused to the upper edge 3a of the bag body 3 by heat sealing, and the step portion 55a of the notch portion 55 functions as a positioning scale to cause flow during heat sealing. The step portion 55a of the outlet 40 is positioned with the positioning scale 3A of the bag body 3 (please refer to FIG. 3). In this manner, by positioning the step portion 55a of the outflow port 40 and the positioning scale 3A of the bag body 3, the outlet port mounting portion 50 of the outflow port 40 can be heat-sealed to the bag body 3 at an accurate position. The bag body 3 and the outflow port mounting portion 50 can be heat sealed at an appropriate angle. Therefore, the bag body 3 and the outflow port mounting portion 50 can be surely heat-sealed to form heat fusion.

In addition, in FIG. 3, each step portion 55 of the notch portion 55 has the same lateral length and the same longitudinal direction (in the vertical direction). Further, the positioning scale 3A of the bag body 3 also has a plurality of step scales 3s having the same lateral length and the same longitudinal direction (in the vertical direction), and the step scales 3s of the positioning scale 3A and Each of the step portions 55a of the notch portion 55 corresponding thereto has the same lateral length and the same longitudinal direction (in the vertical direction). Therefore, when the outlet attachment portion 50 of the outflow port 40 is positioned in the bag body 3, the step portion 55a of the notch portion 55 and the step portions 3s of the positioning scale 3A corresponding thereto are matched-up. Then, by performing the comparison step only by the number of the step portions 55a of the notch portion 55 (for example, the number of layers of 3 to 10), the two directions of the lateral direction and the longitudinal direction (referring to the up and down direction) in FIG. 3 can be performed. The outlet outlet mounting portion 50 of the outflow port 40 is accurately and surely positioned in the bag body 3.

By forming the pair of notch portions 55 in the outflow port attaching portion 50, it is possible to prevent breakage of the bag body 3 due to the outflow port attaching portion 50 during use.

In other words, in the case where "the notch portion 55 is not provided in the thin portion 52 of the outflow port mounting portion 50", the thin portion of the outflow port mounting portion 50 is stored during the operation of storing or transporting the filling or discharging of the content liquid. The corner portion of the 52 is rubbed against the bag body 3, or when the bag body 3 is pressed against the twisted bag body 3, the bag body 3 is damaged, and the content liquid may leak due to breakage.

According to the present embodiment, the notch portion 55 is provided in the lower end corner portion of the thin portion 52 of one of the outflow port attachment portions 50, and the vibration generated during the operation such as storage or transportation, filling or discharging of the content liquid, and the like. The notch portion 55 is strongly rubbed or strongly pressed against the bag body 3, and since the stress is dispersed, it does not concentrate on a single position of the bag body 3, so that the bag body 3 can be prevented from being damaged.

Next, the multilayer film 2 constituting the bag body 3 will be described. In the present embodiment, the multilayer film 2 is composed of "a film constituting the outer bag 20" and "a film constituting the inner bag 21."

As shown in Fig. 10, in the outer bag 20 of the bag body 3, a laminate of undrawn nylon (20 μm thick) 20a and linear low-density polyethylene (thickness 40 μm) 20b may be used. For the inner bag 21, linear low density polyethylene (thickness 70 μm) can be used.

In this case, since the outer bag 20 contains unstretched nylon 20a, therefore, in terms of the outer bag 20, the elongation can be increased, for example, the outer bag 20 has an elongation of 300% to 500%. As a result, since the outer bag 20 can have a large amount of elongation, the bag body 3 can be integrally formed into a soft (soft) state, and the bag body 3 is inserted into the outer package container 5 as will be described later, for the bag body 3 When the bag body 3 is inflated in the outer packaging container by supplying nitrogen or clean dry air inside, the bag body 3 can be smoothly inflated.

The material of the bag body 3 is not limited to the above materials.

For example, the material of the inner bag 21 may also be a material such as low density polyethylene, low density polyethylene, and linear low density polyethylene.

In addition, the material of the outer bag 20 may also be a material having an elongation of 300% to 500%, such as a material such as low density polyethylene and linear low density polyethylene.

Next, the storage state of the liquid storage container 1 toward the outer packaging container 5 will be described. First, a plurality of bellows portions 12 are formed by folding the bag body 3 of the liquid storage container 1 along the longitudinal meander line 11 (Fig. 12). In this manner, the bag body 3 in which the bellows portion 12 is formed is folded by the upper lateral meander line 15a and the lower lateral meander line 15b, and the folded portion 16 is formed (Fig. 13). After that, the bag body 3 is bent along the meander line 13 to form a triangular bent portion 14 (Fig. 14).

In this way, as shown in Fig. 11 (a), (b), and (c), "a plurality of bellows portions 12 and a folded portion 16 are formed in the bag body 3," The liquid storage container 1 of the triangular bent portion 14". The step of forming the bellows portion 12 and the step of forming the folded portion 16 may be performed first, and FIGS. 11(a), (b), and (c) show the state in which the bellows portion 12 is formed first. Herein, for convenience of explanation, the folded portion 16 is omitted in Fig. 12, and the bellows portion 12 is omitted in Fig. 13.

Next, as shown in Fig. 2 (a) and (b), the liquid storage container 1 is folded to form an elongated shape in the longitudinal direction, and the liquid storage container 1 is inserted into the outer packaging container 5 from the opening 5a.

Next, the outflow port 40 of the liquid storage container 1 is attached to the opening 5a of the outer casing 5. In this case, first, the outflow port 40 is rotated with respect to the opening 5a. In this manner, the external thread 41A of the outflow port 40 is screwed into the internal thread 5A of the opening 5a, and the external thread 41A of the outflow port 40 is engaged with the internal thread 5A of the opening 5a. Then, the outflow port flange 42 of the outlet body 41 of the outflow port 40 abuts against the opening 5a of the outer casing 5, and the rotation of the outflow port 40 is stopped.

In this way, the outflow port 40 can be firmly fixed to the opening portion 5a.

In this case, as shown in Fig. 4 (a) and (b), when the outlet 40 of the liquid storage container 1 is attached to the opening 5a of the outer packaging container 5 as will be described later, the liquid storage container is provided. When the bag body 3 of the first bag body 3 is gradually expanded into a flat shape inside the outer casing 5, the width direction of the bag body 3 of the liquid container 1 and the line L3 connecting the first center portion L1 and the opening 5a are formed. In parallel, the internal thread 5A and the external thread 41A are disposed in the following manner: the opening portion 5a of the outer packaging container 5 is from the first The direction in which the center portion L1 is shifted (the left direction in FIG. 4(a)) and the direction in which the outflow port 40 of the liquid storage container 1 is offset from the second center portion L2 (the left direction in FIG. 4(a)) ), facing in the same direction.

In the present invention, the line L3 that connects the first central portion L1 of the outer packaging container 5 and the opening 5a means that when a vertical line extends from the opening 5a toward the first central portion L1. Vertical line. In this case, since the opening 5a has a constant area, it is not necessarily a vertical line passing through the "center when viewed from the opening 5a", and may also include "contacting the edge when viewed from above the opening 5a". The vertical line includes a vertical line between "the center when viewed from the opening portion 5a" and "the edge when viewed from above the opening portion 5a". Further, in the present embodiment, the term "parallel" includes two states in which the two lines are strictly limited to a straight line in addition to the geometrical knowledge, and two in the range in which the effects of the present invention can be obtained. The state in which the line is a curved line, in addition to the fact that the two lines are straight lines and strictly defines the state in which the two lines are not to be intersected, the state in which the effect of the present invention is obtained also includes the state of the two line forming angles (angles). The angle referred to in the "state of the two line forming angles" refers to a state of 20 degrees or less. "The angle is 10 degrees or less" is better, and the "angle is 5 degrees or less" is the best. Further, in the present embodiment, the "same direction" is a state in which the two directions are strictly limited to the same direction, and the two directions are also included in the range in which the effects of the present invention can be obtained ( In the state of the angle, the angle formed by the two directions is 20 degrees or less, and the "angle is 10 degrees or less" is better, and the "angle is 5 degrees or less" is preferable. a specific angle α to be described later, It means an angle other than "the same direction in the present invention" and an angle larger than the definition of the same direction by 20 degrees.

Next, the jig for expansion (not shown in the drawing) is attached to the outflow port 40 of the liquid storage container 1, and the nitrogen gas or the dust-free drying gas is supplied into the liquid storage container 1 by the expansion jig, and the liquid storage container 1 is placed. The bag body 3 is inflated in the outer packaging container 5.

Next, the action of expanding the liquid storage container 1 in the outer packaging container 5 will be described in detail below.

In the case where the liquid storage container 1 has been inserted into the outer packaging container 5, first, the portion of the bag body 3 of the liquid storage container 1 that is lower than the folded portion 16 is dropped by its own weight, after which, "The bellows portion 12 which is folded into the bellows-shaped bag body 3 via the longitudinal meander line 11" acts "returns to a flat force", and the bellows portion 12 of the bag body 3 is gradually expanded into a flat shape.

Next, as described above, the inside of the liquid storage container 1 is supplied with nitrogen gas or a dust-free drying gas by using the jig for expansion, whereby the bag body 3 is inflated. At this time, the bag body 3 which is gradually expanded into a planar shape expands in a vertical direction with respect to the surface of the bag itself.

In this case, since the triangular bending portion 14 formed by bending the meander line 13 is formed above the bag body 3, when the bag body 3 is expanded, the upper edge 3a of the bag body 3 is formed. The corner portion is not hooked to the opening portion 5a of the outer casing 5, and the bag body 3 can be sufficiently expanded in the outer casing 5, and the damage of the bag body 3 can be further prevented.

In addition, since the upper edge 3a of the bag body 3 has two upper edges When the heat seal portion 10a is formed to have a heat seal portion having a large width, the upper edge 3a can be formed softly (softly), and the bag body 3 can be more smoothly expanded in the outer casing 5. Moreover, since the outer bag 20 of the bag body 3 has an elongation of 300% to 500%, the flexibility of the bag body 3 can be improved, and the expansion of the bag body 3 can be easily performed.

Further, when the outflow port 40 of the liquid storage container 1 has been attached to the opening portion 5a of the outer package container 5, the bag body 3 of the liquid storage container 1 is inside the outer package container 5, and gradually expands into a flat shape as described above. . At this time, the width direction of the bag body 3 is parallel to the straight line L3 connecting the first central portion L1 and the opening 5a of the outer casing 5, and the opening 5a of the outer casing 5 is offset from the first central portion L1. The direction of the movement is oriented in the same direction as the "direction in which the outflow port 40 is offset from the second central portion L2". Therefore, even if the opening 5a is displaced from the first central portion L1 of the outer packaging container 5 and the outflow port 40 is displaced from the second central portion L2 of the liquid storage container 1, the bag body 3 of the liquid storage container 1 can be used. The bag body 3 of the liquid storage container 1 is surely expanded in the outer packaging container 5 by supplying nitrogen gas or a dust-free drying gas therein (refer to Fig. 4(a)). In other words, since the width direction of the bag body 3 of the liquid storage container 1 is parallel to the straight line L3 that connects the first central portion L1 and the opening 5a of the outer packaging container 5, the bag body 3 of the liquid storage container 1 is provided. The width direction is oriented in the same direction as the diameter direction of the outer packaging container 5. When the bag body 3 is inflated in the outer packaging container 5, since the bag body 3 is expanded in the vertical direction with respect to the surface of the bag body 3, the width direction of the bag body 3 of the liquid container 1 and the diameter direction of the outer package container 5 are oriented. In the same direction In this case, the expansion space of the bag body 3 of the liquid storage container 1 in the outer package container 5 becomes the largest. Further, in this case, when the bag body 3 of the liquid storage container 1 is inflated, the bag body 3 is hooked on the inner wall of the outer casing 5 or bent by the inner wall to partially expose the bag body 3. The closed condition is suppressed to a minimum, and the inner volume of the bag body 3 can be sufficiently ensured.

In addition, as shown in the comparative example, the bag body 3 is not parallel to the "line L3 connecting the first central portion L1 and the opening 5a of the outer packaging container 5" in the width direction of the bag body 3 of the liquid storage container 1. In the case where the width direction forms a specific angle α with the straight line L3, the width direction of the bag body 3 does not coincide with the diameter direction of the outer casing 5, and the expansion space of the bag body 3 in the outer casing 5 is reduced. When the bag body 3 of the liquid storage container 1 is inflated in the outer casing 5, the bag body 3 abuts against the inner wall of the outer casing 5, the part of the bag body 3 is closed, and the bag body 3 is twisted. The bag body 3 is not sufficiently inflated (refer to Fig. 4(b)). Further, as shown in the comparative example, the outflow port 40 of the bag body 3 of the liquid storage container 1 is attached to the second center portion L2 of the bag body 3, and the opening portion 5a is offset from the first center portion L1 of the outer package container 5. In this case, the position of the first central portion L1 of the outer packaging container 5 and the second central portion L2 of the bag body 3 are shifted. For the above reasons, the same disadvantage occurs, so that the bag body 3 cannot be sufficiently inflated (refer to Fig. 4(c)).

On the other hand, in the present embodiment, the width direction of the bag body 3 is parallel to the "straight line L3 connecting the first center portion L1 and the opening portion 5a of the outer casing 5", and the opening portion of the outer casing 5 The direction "5a offset from the first central portion L1" and the "direction in which the outflow port 40 is offset from the second central portion L2" are oriented in the same direction. Therefore, the width direction of the bag body 3 of the liquid storage container 1 and the outer packaging container The diameter direction of 5 faces the same direction. Accordingly, when the bag body 3 of the liquid container 1 is inflated in the outer packaging container 5, the bag body 3 does not abut against the inner wall of the outer container 5, and the expanded bag body 3 can be hooked. The case of the outer packaging container 5 is suppressed to a minimum. Therefore, in the outer package container 5, the bag body 3 can be accurately and surely expanded without being closed and twisted, and a sufficient internal volume can be secured.

In this way, a combination of the outer packaging container and the liquid storage container can be manufactured. After that, the jig for expansion is detached from the outflow port 40, the content liquid filling machine (not shown in the drawing) is attached to the outflow port 40, and the content liquid is filled from the content liquid filling machine toward the liquid storage container 1.

After the content liquid is filled in the liquid storage container 1, the outlet upper member 70 for holding the liquid dispensing nozzle 60 is attached to the "outflow port of the opening 5a of the outer packaging container 5, as shown in Fig. 3". In the outlet body 41 of 40, the liquid dispensing nozzle 60 is inserted into the outlet upper member 70. The outflow port upper member 70 may also be integrally formed with the outflow port 40.

The liquid dispensing nozzle 60 inserted into the outflow port upper member 70 extends through the through hole 45 of the outflow port 40 toward the inside of the bag body 3 of the liquid storage container 1. Further, the liquid dispensing nozzle 60 has a large-diameter portion 63 formed at an upper end thereof and a dome-shaped portion 61 formed at a lower end thereof, and a plurality of openings 62 are formed in the dome-shaped portion 61. The dome shape 61 is formed in a hemispherical shape, and a plurality of openings 62 are formed in the hemispherical surface.

The liquid distribution nozzle 60 inserted into the outlet upper member 70 has the large diameter portion 63 provided at the upper end thereof engaged with the outlet upper member 70 and held by the outlet upper member 70.

In this way, after the step of filling the content liquid into the liquid storage container 1 is completed, the lid (not shown in the drawing) is attached to the opening 5a of the outer packaging container 5. At this time, between the cover and the outflow port upper member 70, a sealing member called a break seal is interposed (when a dispenser (not shown in the drawing) to be described later is attached, The front end of the dispenser is pierced and does not produce debris and can penetrate through the thick film). Therefore, the outflow port 40 and the liquid dispensing nozzle 60 are sealed by the break seal and the lid. As a result, the outflow port 40 and the large diameter portion 63 of the liquid dispensing nozzle 60 are sealed. In this case, the cover is engaged with the external thread 5b provided on the outer circumference of the opening 5a. Further, the cover is formed by the cover body and the upper cover, and the upper cover is detachable from the cover body.

When the content liquid in the liquid storage container 1 is discharged to the outside, the upper cover is detached from the cover main body, and the large-diameter portion 63 of the liquid dispensing nozzle 60 is connected to the dispenser via the break seal and the cover body.

Next, nitrogen gas is supplied from the pressurized gas source (not shown in the drawing) to the outlet body 41 of the outflow port 40 via the "opening 71a formed between the dispenser and the flange 71", after which nitrogen gas is supplied from The opening 44 enters a space between the "outer packaging container 5 and the bag body 3 of the liquid storage container 1". Next, the bag body 3 is pressed by nitrogen gas from the outside to make the bag body 3 The content liquid enters the liquid dispensing nozzle 60 from the opening 62 of the dome-shaped portion 61, and the content liquid in the liquid dispensing nozzle 60 is then discharged from the large diameter portion 63 toward the dispenser side.

Since the residual liquid that has not been discharged from the liquid storage container 1 becomes a waste object, the resource is too wasteful. According to the invention of the present invention, when the bag body 3 of the liquid storage container 1 is inflated, the bag body 3 can be hooked. When the inner wall of the outer casing 5 and the inner wall are bent, the part of the bag body 3 is closed to a minimum, and therefore, a highly expensive content liquid such as an industrial medicine is discharged. In this case, the amount of residual liquid can be reduced, and the cost can be reduced by saving resources.

Here, the dispenser has a liquid flow path for discharging the liquid from the liquid storage container 1 at the center, and further has a gas for feeding nitrogen gas or the like between the liquid storage container 1 and the outer packaging container 5. Gas flow path.

Since the liquid dispensing nozzle 60 has the dome-shaped portion 61 at its lower end, even when the content liquid in the bag body 3 is discharged outward from the large-diameter portion 63 via the liquid dispensing nozzle 60, even if the lower end of the liquid dispensing nozzle 60 abuts The bag body 3 can also be prevented from being damaged by the lower end of the liquid dispensing nozzle 60 by being attached to the inner surface of the bag body 3.

Further, the content liquid of the bag body 3 is sucked into the liquid dispensing nozzle 60 via the plurality of openings 62 provided in the dome-shaped portion 61, and is discharged from the large diameter portion 63 toward the dispenser side. Therefore, compared with the case where a single opening is provided at the center of the lower end of the liquid dispensing nozzle 60, even if the residual amount of the content liquid becomes small, the bag body 3 can be prevented from being closely attached to the liquid dispensing nozzle. 60, the flow of the content liquid toward the inside of the liquid dispensing nozzle 60 becomes difficult.

Next, other aspects 1 and 2 of the liquid dispensing nozzle 60 will be described.

<Other Aspect 1> As for the liquid dispensing nozzle 60, a type of the through hole 45 that is screwed to the outflow port 40 may be employed. In other words, "the outflow port 40 having the screw groove on the inner circumferential surface of the through hole 45" and the "liquid dispensing nozzle 60 having the external thread on the outer end surface" may be prepared to engage the external thread of the liquid dispensing nozzle 60. The thread groove of the outflow port 40. In this aspect, the outflow upper member is not required. In this case, a screw groove is provided in the inner peripheral surface of the upper end of the liquid dispensing nozzle 60, and the dispenser having the external thread is directly screwed to the thread groove.

In the other state 2, a screw groove may be provided in the inner circumferential surface of the through hole 45 of the outflow port 40, and a protruding portion facing the inner side may be provided at the lower end of the through hole 45. In this case, a locking flange that protrudes outward is provided at the upper end of the liquid dispensing nozzle 60, and the locking flange is locked to the protruding portion of the through hole 45. At this stage, although the liquid dispensing nozzle 60 is not fixed to the outflow port 40, the liquid dispensing nozzle 60 can be fixed by directly screwing the dispenser to the thread groove of the inner peripheral surface of the through hole 45.

In the other aspects 1 and 2 described above, the lower end of the liquid dispensing nozzle 60 may have a dome-shaped portion which is formed in a hemispherical shape, and a plurality of openings may be formed in the hemispherical surface.

The lid of the opening cover (other aspect 1) or the lid that "locks the through hole 45 of the outflow port 40 to cover the through hole 45" (other aspect 2). In the other aspects 1 and 2 described above, the sealing member such as the rupture seal is not used, and the dispenser is directly screwed to the upper end opening of the liquid dispensing nozzle when the content liquid is discharged (other states 1), Or the through hole of the outflow port (other aspect 2).

Further, in the other aspects 1 and 2 described above, the means for discharging the liquid is not in a form of pressurizing the liquid storage container 1, but is formed by connecting the liquid storage container 1 and the dispenser, and then attaching The pump on the dispenser side sucks and discharges the liquid in the liquid storage container to the outside.
